Abstract: ABSTRACT OF THE DISCLOSURE            An improved electron gun support structure and method provides for the firm mounting of an electron gun in the neck of a cathode ray tube.  Manufacturing assembly of the gun is simpli-fied and the yield is increased.  Further, the improved structure promotes the establishment and maintenance of coincident align-ment of the gun with the tube central axis, and improves rotational alignment.  The gun support structure includes a plate mounted adjacent the base of the tube, which plate may carry or support electrical conductors serving as sections of a network of elec-trical interconnections between lead-in pins in the base and electrically excited gun components.  The plate may also act as a shield against arc-inducing cathode sublimation deposits.

Abstract: LIGHT EMITTING DEVICES     Abstract of the Disclosure A light emitting device has a III-V compound semi-conductor substrate whose bandgap is wider than the energy range corresponding to the radiation emitted by the device and which has a predetermined conductivity type.  A second III-V compound semiconductor layer is deposited on an upper surface of the substrate and has the opposite conductivity type to that of the substrate.  A current control layer covers an upper surface of the second layer and has a hole for current flow.  A first electrode is provided on the current control layer and is in ohmic contact with the second III-V compound semiconductor layer.  An ohmic contact electrode is provided on a bottom surface of the substrate and has a light extracting window at its central part.  The current control layer is made of a layer of high carrier concentration having the opposite conductivity type to that of the second III-V compound semiconductor layer.  The arrangement avoids a prior art difficulty in which the radiation region becomes extended by reason of the "current spreading phenomenon and becomes larger than the hole for current flow in the current control layer.  Avoidance of this difficulty increases the efficiency of the device and especially enables efficient coupling with an optical fiber.

Abstract: An apparatus for heating a liquid using solar energy is described. Through the use of a corrugated absorber plate made of a sheet of copper or any similar conductive metal, the heat from the sun is captured. The front surface of the plate may be covered with a dark absorbent coating. The heat absorbed by the copper sheet is conducted to a thin film of liquid such as water which is fed by gravity down the backside of the plate from a supply line disposed adjacent to the top of the backside of the plate. The liquid absorbs the heat from the plate as it flows downward covering the backside of the plate and is discharged at the bottom of the plate into a drain line.  The drain line removes the heated liquid from the apparatus.

Abstract: CRUISE ECONOMY SYSTEM            ABSTRACT  OF THE DISCLOSURE          A closed loop integral control system for the air/fuel management of an internal combustion engine is disclosed.  An oxygen sensor positioned in the exhaust gas of the internal com-bustion engine is biased with a constant current source to provide a signal indicative of the oxygen content of the exhaust gas over a significant range of air/fuel ratios.  The signal waveform from the sensor is compared to a threshold value of a comparator to produce level changes in the comparator output depending on whether the output of the sensor is above or below the threshold.  An integrator, receiving these level changes as commands to increase or decrease the fuel pulse widths, controls the air/fuel ratio of the engine in a limit cycle around a scheduled value.  By changing the current bias on the sensor and thus modifying the unbiased waveform of the sensor to intercept the threshold value at various points different average air/fuel ratios are obtainable from the system.  According to another feature of the invention, cruise detection circuitry determines when the engine is in a stable non-accelerating/decelerating mode and enables the current source to bias the sensor to produce a relatively lean air/fuel ratio from the system for an economical optimum cruising operation.
